Particle-in-Cell (PIC) plasma simulation codes model the interaction of
charged particles with surrounding electrostatic and magnetic fields.
PIC's computational requirements are classified at as one of
the grand-challenge problems facing the high-performance community.
In this paper we present the implementation of 1-D and 2-D electrostatic
PIC codes in High Performance Fortran (HPF) on an IBM SP-2. 
We used one of the most successful commercial HPF compilers currently 
available and augmented the compiler's missing HPF functions with
extrinsic routines when necessary. 
We obtained a near linear speed-up in execution time and 
a performance comparable to the native message-passing implementations  
on the same platform.

\noindent {\bf Keywords:} Particle-in-Cell, High Performance Fortran.
